INVITED FAֱLTY TALK - The “Teflon Basin” Myth Debunked: Most Snowmelt Runoff Is “Old” Water And Not “New” Water

Williams , Mark W 1 1 INSTAAR and Geography New research shows high-altitude aquifers honeycomb parts of the ֱ Rockies, trapping snowmelt and debunking the myth that high mountain valleys act as “Teflon basins” to rush water downstream. In much of western North America, snow and snow melt provides the...

INVITED TALK: From Research To Remediation: Some Applications Of Hydrogeochemical Research To Mine Site Remediation

Nordstrom , D. Kirk 1 1 U.S. Geological Survey, Boulder, CO Research in chemistry, geochemistry, and hydrogeochemistry has been applied successfully to identify the geochemical processes that produce acid rock drainage and determine its fate, and to understand remediation scenarios. When iron in acid drainage fully oxidizes, does the pH...

INVITED FAֱLTY TALK - Applications Of Wavelet Analysis In Hydrology

Neupauer , Roseanna M 1 1 Univ. of ֱ Wavelet analysis is a relatively new tool for data analysis and signal processing. Similar to Fourier analysis, wavelet analysis identifies dominant periods or scales in one-dimensional and multi-dimensional data sets. The key difference between Fourier analysis and wavelet analysis is in...
